Managing rotation

I have a pose ball that, after an av sits on it, is turned to physical and then moved successively to 3 or 4 different waypoints down a slide with llMoveToTarget. Everything works pretty well except for the fact that the av is rolling all around the whole time (upside down, right side up, etc. - much like the ball would be doing in rl I guess). I realize that I may have to do some work to keep him facing in the direction of movement but, before I do that, how do I at least keep him sitting upright?

I don't know if it will solve your problems, but you should be able to keep them upright by setting the x and y rotations to false, turning to face travel is trickier.

That looks promising - I'll give it a try - thanks!

using a simple llLookAt(llGetVel+llGetPos()) in a timer loop should keep the ball looking in the direction it's traveling. that plus may need to be a minus, and/or the vel switched around with pos, but I don't have acess to SL right now and can't think through the math ATM.
